Answer 1

Answer:

[-5,1] or [-4,5]

Step-by-step explanation:

Here, we want to get the intervals over which there is an average rate of change of zero for f

For this to happen, over the given interval, there will not be a change in the y-axis value

What this mean is that the y-axis value will remain the same over this given interval

for x = -5 to x = 1, we have this

for x = -4 to x = 5 , we have this

a recipe calls for 5/8 cup of sugar for every 5 teaspoons of vanilla. what is the unit rate in cups per teaspoon?

a) 3 1/8
b) 1/8
c) 8
d) 8/25

Answers

Answer:

b) 1/8

Step-by-step explanation:

5/8 ÷ 5 = 1/8

The unit rate in cups per teaspoon is 1/8 cup of sugar.

What is the unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

5/8 cup of sugar=5 teaspoons of vanilla.

or, 5 teaspoons of vanilla = 5/8 cup of sugar

So, 1 teaspoon of vanilla = (5/8)/5 cup of sugar

(5/8)/5 = (5/8)*(1/5)

(5/8)/5 =1/8

So, 1 teaspoon of vanilla = 1/8 cup of sugar

Hence, the unit rate in cups per teaspoon is 1/8 cup of sugar.

While attending a major league baseball game, you think you can guess the
attendance within 10% of the actual value. If the announced attendance is
35,000, within what number of people would your guess have to be in order for you to support your claim?

Answers

Answer:

You would have to have guess a number larger than 31500 and smaller than 38500

Step-by-step explanation:

The answer will look something like

35000 +/- 10% (35000)

What that means is that the attendance would be smaller than 35000 or larger than 35000.

10% * 35000 = 10/100 * 35000 = 350000 / 100 = 3500

So you would have to estimate

35000 - 3500 ≤ attendance ≤35000 + 3500

31500 ≤ attendance ≤ 38500

Answer:

a) 16.4 kmb) 79°c) 10 km

Step-by-step explanation:

Find the m∠B:

m∠B = (360° - 310°) + 50° = 100°

Find AC using law of cosines:

AC = √(8² + 13² - 28*13*cos 100°) = 16.4 km (rounded)

Find m∠A using law of sines:

16.4/ sin 100 = 13 / sin Am∠A = arcsin (13 sin 100 deg / 16.4) = 51° (rounded)

The bearing of C from A:

180° - (50° + 51°) = 79°

Let the required distance is x:

x/ BC = sin 50°x = BC sin 50°x = 13 sin 50°x ≈ 10 km (rounded)

can you use the term parallelogram to describe a rectangle

Answers

Answer:

Yes. In order for a shape to be qualified as a parallelogram It has to have 4 main properties. Opposite sides are parallel. Opposite sides have to be congruent. The opposite angles are congruent. Consecutive angles are supplementary (adds to 180-degrees). A rectangle qualifies all of these properties for a parallelogram. Opposite sides are parallel which works for a rectangle since they never intersects with the oppposit line. Opposite sides are congruent or equal which is also true becuase when looking at any 2 opposite sides of a rectangle, its always gonna be equal. Opposite angles are congurent which is also true because their all 90 degrees all are equal. And finally consecutive angles add up to 180. Soncsuive int his case basically means the angle next to that angle but we don’t have to worry about that since all angles of a rectangle are 90 and 90+90=180 so it also DOES qualify for a parallelogram.
